I think there may be commercial items that do the same thing.

That is really slick! There is probably a small market for that.

On my points distributor, it was an estimated 0.0125" per distributor degree.

My slot length measured 0.375".

With a pin/bushing diameter of 3/16" (0.1875) I had 15 degrees at distributor, which was higher than my target.

I used a Moroso press-on bushing, with 0.25" OD. This resulted in 11 degrees advance at distributor, 22 @ crank, and I called it good.
